<h1 class="header">Configuration</h1>
<h2 class="header">Mandatory</h2>
This SPI has no mandatory configuration parameters.
<h2 class="header">Optional</h2>
This SPI has following optional configuration parameters:
<ul>
<li>Cache name (see <a href="../../../../../../org/apache/ignite/spi/checkpoint/cache/CacheCheckpointSpi.html#setCacheName-java.lang.String-"><code>setCacheName(String)</code></a>)</li>
</ul>
<h2 class="header">Java Example</h2>
<a href="../../../../../../org/apache/ignite/spi/checkpoint/cache/CacheCheckpointSpi.html" title="class in org.apache.ignite.spi.checkpoint.cache"><code>CacheCheckpointSpi</code></a> can be configured as follows:
<pre name="code" class="java">
IgniteConfiguration cfg = new IgniteConfiguration();
String cacheName = "checkpoints";
GridCacheConfiguration cacheConfig = new GridCacheConfiguration();
cacheConfig.setName(cacheName);
GridCacheCheckpointSpi spi = new GridCacheCheckpointSpi();
spi.setCacheName(cacheName);
cfg.setCacheConfiguration(cacheConfig);
// Override default checkpoint SPI.
cfg.setCheckpointSpi(cpSpi);
// Start grid.
G.start(cfg);
</pre>
<h2 class="header">Spring Example</h2>
<a href="../../../../../../org/apache/ignite/spi/checkpoint/cache/CacheCheckpointSpi.html" title="class in org.apache.ignite.spi.checkpoint.cache"><code>CacheCheckpointSpi</code></a> can be configured from Spring XML configuration file:
<pre name="code" class="xml">

...
&lt;!-- Cache configuration. --&gt;
